摘要 分析了几种常见的LM S算法,并通过理论分析,提出了一种变步长并行LM S算法,提高了LM S算法的收敛速度,使其适应高速数据处理需求。研究了变步长并行LM S算法的原理和具体实现步骤,同时通过变换算法的特性参数进行了MATLAB仿真研究,结果表明该算法具有一定的先进性。 Some algorithms of LMS were discussed and a variable step size parallel LMS algorithms were put forward based on theoretical analysis, which can improve the convergence speed of the LMS algorithms and make it meet the need of high speed data processing. The principle and concrete completing steps of this LMS algorithms were researched. At the same time the algorithms were simulated with the MATLAB by changing characteristic parameter. The advantages of the variable step size parallel LMS algorithms were proved by results.
